LTC3428 - 2MHz Dual Phase Step-Up DC/DC Converter

Description

The LTC®3428 is a 2-phase, current mode boost converter, capable of supplying 2A at 5V from a 3.3V input.

Two 93mΩ, 2A N-channel MOSFET switches allow the LTC3428 to deliver high efficiency from input voltages as low as 1.6V.

Features

  • n High Efficiency: Up to 92% n 2-Phase Control Reduces Output Voltage Ripple n 5V at 2A from 3.3V Input n 3.3V at 1.5A from 1.8V Input n 1.6V to 5.25V Adjustable Output Voltage n 1.6V to 4.5V Input Range n Internal Soft-Start Operation n Low Shutdown Current:.
